The REF_TW_BCR601_55V_0.5A tunable white reference design uses BCR601 and BCR602 linear regulators to provide stable LED current without ripple or fluctuations. BCR601's active headroom control (AHC) maximizes efficiency similar to switched-mode regulators. BCR602 in a tiny SOT23-6 package regulates LED current for flicker-free deep dimming. A modular reference design with XDPL8219 board is available.

Features

  • BCR601 as the master controller controls the voltage overhead of both channels and current of one channel
  • BCR602 as slave controller regulates the current of the second channel
  • Input voltage up to 60 V
  • Can be operated with either BJT or N-channel MOSFET
  • Analog dimming down to 3 %, PWM dimming down to 1 % (BCR602)
  • Current precision ±3 %
  • OTP, OVP, hot-plug protection

Benefits

  • Linear regulators give considerable cost advantage over buck topology
  • Cost advantage increases with additional channels
  • Efficiency can be on par with the buck (depends on output ripple of the first stage)
  • Highest light quality, zero ripple
  • Deep, full analog dimming
  • Easy to extend to additional outputs (e.g. RGBW)
